Contenders' BBC debate

In front of a left wing BBC, 'impartial' audience, Nigel Farage, the UKIP leader, was up against four candidates whose policies were EXCLUSIVELY focused on spending English taxpayers' money. Let's look at the four opposition leaders:

Nicola Sturgeon.     SNP.  Scottish independence for 5m Scots
Leanne Wood.        Plaid Cymru.  Welsh nationalists.
Ed Miliband.           Labour.  First generation immigrant wanting to tell the British how to behave.
Natalie  Bennett       Green Party.   Immigrant wanting to tell the British how to behave.

What a bunch! How can it be right that these people are vying to represent the interests of the British people, the majority living in England and most likely to pay the lion share for the wants of the others? What about the indigenous English, Anglo Saxon families whose ancestors have lived in the country for thousands of years, sharing in the cultural, scientific and artistic development? Have they no voice?
And what about the impartial audience? The BBC wouldn't recognise one if it hit it in the face.
